Investigators say an argument turned violent between the Ownbeys and another couple after heavy drinking on May 19. The homeowner, who also is a Denver police officer, asked the Ownbeys to leave, at which point investigators say Jamie Ownbey struck the other wife from behind. The officers then started fighting.

Investigators say the officers acknowledged they and their wives trade sex partners, but they denied sex sparked the brawl.

Prosecutors say the Ownbeys also left their two young children home alone during the dinner, prompting the child abuse charges.
